There is plenty of debate about oil products and change intervals. Please post your change interval (months and miles), oil type (viscosity and brand), and filter (brand and composition), and any observations you would like to add.

Dealer oil change every 5 K miles with synthetic 0-w20 on this LS. I know I can go longer OCI but why?
It's not expensive and you drive a luxury car.
I drive 12 K miles annually so I basically have it done every 5 months.
All my other cars are DIY oil changes with full synthetic oil and I follow the manufacturer's OCI schedule as well.
I feel the car runs and shifts smoother with new engine oil.

I'm going with the manufacturer recommended 10K interval right now. Dealer did the first one (free) and I did the second one myself. Toyota 0W-20 full synthetic and Toyota filters (local Toyota dealer had a sale on filters for $4@ - I bought 5). I drive 15-20K/year so miles rather than months is always the driver. I have never done it before, but may send used oil out for analysis after next change. I'll admit to being a little nervous about a 10K interval - I've been changing on a 5K interval on all my vehicles for decades! 5K interval seems to work OK - I routinely have run vehicles to 250-300K miles regardless of manufacturer (Fords, Lincolns, Toyotas, Nissans).

I've used the following oils:
Castrol 0w20-met requirements
Mobil1 0w30-too early to tell but no weird startup noises (34mpg@70mph).
Royal Purple 5w30-pretty good/no noises but I dumped it at 4,500 miles/very good mileage

What the manual says. TGMO 0w20 every 5000 miles or 1 year (it will be close for me which comes first). Next change due at 48,000 or in April.

Just did my oil change today at 10k miles. Sending my sample to Blackstone Labs for analysis. TGMO 0W20

Previous oil change was done at 8k miles on the same oil and the Lab results came back great. 10k should be good too.

how much is it to send oil to lab?

roadfrog

It's about 28 bucks:

The manual doesn't exactly say that; the manual says this (2008):

http://drivers.lexus.com/lexusdriver...nual-search.do

Use Lexus approved “Toyota Genuine Motor Oil” or
equivalent to satisfy the grade and viscosity shown
below. 5w20 or 0w20 All climates.
The 0W portion of the oil viscosity rating indicates a characteristic of the
oil which allows cold startability. Oils with a lower value before the W
allow for easier starting of the engine in cold weather.
l The 20 in 0W-20 indicates the oil viscosity when the oil is at its operating
temperature. An oil with a higher viscosity may be better suited if the
vehicle is operated at high speeds, or under extreme load condition.

I do not operate my LS at high speeds or under extreme load conditions. No towing, no cruising at autobahn speeds, and I live in a mild climate.

superdenso

The authorities that regulate the autobahn recommend speeds between 60-80mph. There may be some confusion between what individuals think is high speed and what traffic regulators consider high speed.

Mobil 1 Synthetic 0W-20 and OEM Lexus filter every 10k miles (90% highway driving). 130,xxx miles and going strong.

Thanks for sharing your extended oil change interval data.

I usually do my 1st change at 2500 miles and every 7500 after that.

on a side note; My wifes new RR Sport has a recommended OCI at every 16,000 miles.

I ran my 91LS on 15k intervals for the Oil and 5K intervals for the filter with no issues. I soon plan on doing the same with my new 2010LS. Oil will be Mobile 1 Full Syn W/Lucas Syn additive.
